Search for the rare decay

Using a data set with an integrated luminosity of $$2.93\text{ }\text{ }{\mathrm{fb}}^{{-}1}$$ collected at $$\sqrt{s}=3.773\text{ }\mathrm{GeV}$$ with the BESIII detector operating at the BEPCII storage rings, we search for the rare decay $${D}^{+}{\rightarrow}{D}^{0}{e}^{+}{{\nu}}_{e}$$. No signal events are observed. We set the upper limit on the branching fraction for $${D}^{+}{\rightarrow}{D}^{0}{e}^{+}{{\nu}}_{e}$$ to be $$1.0\times{}1{0}^{{-}4}$$ at the 90% confidence level.
